FORGE-FEED OILER.

Specification of Letters Patent.

Patented Dec. 24, 1907.

Application filedMarch 5. 1907. Serial 50. 360,730.

To all whom it may concem:

,Be it known that I, IGEORGE VVoon, a

citizen of the United States, residing V at. Newark, in the county of Essex and Stateof New Jersey, have invented certain new and useful improvements in Force-Feed Oilers'j;

tion, such as will enable others skilled'in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, and to lettersof reference marked thereon, which form a part of this specification.

This invention relates to a lubricator, and is of the class known as force feed oilers, and is designed for use particularlyon the motors of auto-vehicles, motor boats, and all gas motors, and for lubrication of every descri )tion where force is used, transmitted from this mechanism being driven, to feed oil to the wearing parts.

The invention is designed toprovide an oiler, of this kind, that is very cheap to make, and its simplicity insures its constant operation. v

.The oiler also embodies a construction that can he installed on any part of the machine, and has various means for adapting itself to being driven from either side or end of its casing. p

The invention also provides an oiler, of this kind, that if it should be accidentally driven backward, will not tend to break or destroy any of the parts, as there is provision made for taking up any motion in reverse direction and relieving the pumps of any strain.

The invention is illustrated in the accompanying drawing, in which Figure 1 is a plan view of the oiler with the cover removed. Fig. 2, 2, in Fig. 1. Fig. 8 is a view similar to Fig. 2, but showing only a portion of the device, and illustrating the ump in the position where it is about to fdrce some oil from the oiler. Fig. 4 isa detail section of the connection between the oil tube, leading to the element to be lubricated, and a connection with the casing of the oiler.

In the drawings the casing 10 is provided with bearings 12 in which is arranged a shaft 11. On either side of the shaft 11 can be placed a pulley 13 that adapted to receive motion, by means of a belt or other transmitting medium, from some moving part of 2 is a section on line I the machine, and in this way a worm-wheel "14 is caused to operate, at a slower s eed, a "gear wheel 15 which is mounted on a s aft 16. This shaft 16 rotates in the standards- 17 which are slotted at the top, and receive blocks 18 hearing on the top of the shaft 16. Spring keys 19 pass through the elements to hold the blocks 18 down fast on the shaft 16. It is thus seenithat this shaft 16 has a slow steady rotary motion, and it thus carries around with it, studs 20, the function of these studsbein-g described hereinafter.

Parallel to the shaft 16 is a rod 21 whichis mounted in the standards 22, secured to the bottom of the casing, and this rod. 2.]. is pro vided. with levers 23 on top of one end of each of which is placed the plate 24, made of hard steel, "to take up the wear from the studs 20 which engage them, and on the other ends of the levers 123 is the forked portion 25, each of the forked ends 25 of the levers 23 engaging a collar 27 fastened to the piston 26. The piston 26 is forced downward by means of a spring28, between t-he'collar 27 and a web 29 in the casing, and a second spring 30, arranged below the forked end of the lever 23, around each piston 26, engages the top edge of a tubular portion 81., which portion is an enlargement of the casting of which the casing is made, although this preferred form might bedeparted from, and the tubular'p'or- J tion 31, forming the pump casing, mightbe attached to the casing and made of a separate piece of material. As the shaft 16'revolves, the studs 20 engage the plate 24 of each lever 23 and press down one end, shown in Fig. 3. This pushes the piston 26, of each pump, upward against the action of the spring 28, and the lower end of the piston uncovers a perforation 32 which forms an inlet to the pump from the casing, and a small quantity of oil is thus drawn into the bore in which the piston 26 operates. As each stud 20 passes over the edge of the plate 24 of each lever 23, the spring 28 snaps the piston in each pump sharply downward, and

a small quantity of oil is thus forced from the casing down into an oil tube to be described hereinafter.

The action of the spring is so swift and sharp that the oil isforccd down from the casing in a positive manner, and the feeding of the oil is assured. instead of all the'studs 20 being arranged in line. asshown in Fig. l, theymight be staggered circunifcrentially so that the pumps will be successively operated,

as will be understood. If by chance the oiler of the spring 30, and after the studs 20 have passed beyond the lever 23, the spring 30 will ring the forked end of .the lever back into p ace, and there will he no damage resulting.

At the bottom of each pump is screwed a nut 33 having a threaded portion extending therefrom, and in the portion. 33 is a screw 34 by means of which the flow of oil through the tube can be increased or diminished. ()n the threaded extension of the nut 33 is arranged a union 35 which bears up against a conical head 36 having a stem 37, both of these elements being longitudinally bored to furnish a passage for oil, and the conical head 36 is forced up into a recess 38 in the nut 33, and a tight joint is the result. A copper or similar tuhe 39 can then be passed over the stem 37 and secured thereto, in any well known manner, and each of these tubes 3% can be led oif to the pointto be lubricated, as is now common in machines of this class. A modified. form however can be installed, as shown in l ig. 4, where a tube 40, which ean be made of glass or quartz or similar pump cylinders in the casing, a reciprocating transparent material, fits over the stem 37 and is secured thereto by suitable sealing matter 41, and the oil tube 39 is fitted into the other en of the glass tube, this construction forming a sight glass whereby the end of the stem 37 can be observed to ascertain whether the feeding oi oil is really taklace. v

i T is casing is provided with a cover 43 which can be suitably perforated at the top and provided "with a swinging lid 42.

One of the principal advantages of this construction of oiler is its'extreme simplicity, and this taken in conjunction with its 1 isitive action, provides a lubiicatin me lanism that is very desirable.

Having thus described my invention, What I claim is:---

1. An oiler comprising a casing, a series of piston in each pump cylinder and projecting therefrom, a spring encircling each. piston l r and bearing thereon, the other end or the spring bearing on the casing, a lever engaging each piston, and means for 1nd1vidually engaging each le r to compress the spring and then to release the lever to allow the spring to opera "e the pump.

2. An oiler comprising a casing, a series of pump cylinders in the casing, pistons 1n the pump cylinder andpro ectmg therefrom, a spring engaging each piston and adapted to operate it, a lever for each piston for ,compressing the spring, and means ior operating and releasing the levers.

snare 3. An oiler comprising a casing, a series of pump cylinders therein, a piston in each pump cylinder and projecting therefrom, a spr ng on each piston, levers pivoted in. the

casing, one lever engaging each pump piston,

a shaft adapted to rotate in the casing, and studs on the shaft, each stud being arranged with a lever in its path of travel.

5. An oiler comprising a casing, a series of pump cylinders therein, a lever engaging each pump cylinder, spring on each pump, a second spring on each pump to receive the reverse motion of its lever, and means for pump cylinders in the casing, a piston in each pump cylinder, a pair of springs on each piston acting against one another to hold the piston in its normal position, levers, one for each piston to actuate it, and shaft having studs thereon to operate the levers.
